C# Memory Management & Garbage Collection: The Technical Interview Masterclass
Master C# memory management and Garbage Collection for senior technical interviews. Learn stack vs heap, GC generations 0-2, LOH fragmentation, and trap questions.
Welcome to CodeToClarity, a publication dedicated to demystifying modern software engineering, .NET architecture, AI systems, and the principles that help developers write resilient software.
Master C# memory management and Garbage Collection for senior technical interviews. Learn stack vs heap, GC generations 0-2, LOH fragmentation, and trap questions.
Master Redis fundamentals. Explore in-memory storage, single-threaded reactor loops, 5 core data structures, Cache-Aside caching, and production pitfalls.
Master MongoDB fundamentals. Learn BSON internals, ObjectId anatomy, embedding vs referencing, atomic operators, and building high-performance aggregation pipelines.
Learn how SQL Server organizes relational storage. Master 8KB data pages, extents, heaps vs clustered indexes, and B-Tree seeks to eliminate slow queries.
Master zero-downtime database migrations in Kubernetes with EF Core and GitHub Actions. Implement the Expand-Contract pattern, isolated Jobs, and lock guards.
Master PostgreSQL EXPLAIN (ANALYZE, BUFFERS). Learn Volcano plan nodes, fix work_mem disk spills, diagnose sequential scans, and tune slow production queries.
Master Span<T> and Memory<T> in C#. Stop heap allocations and GC spikes, understand ref struct internals and async boundaries, and build high-throughput APIs.
